thanks for your reply. Here is my login code:

BFGlobalService bfGlobal = new BFGlobalService();
LoginReq request = new LoginReq();
LoginResp resp;

request.username = username;
request.password = password;
request.productId = 82;
request.vendorSoftwareId = 0;
request.locationId = 0;
request.ipAddress = “0″;

resp = bfGlobal.login(request);

The object ‘resp’ has an attribute called ‘header’ and this is null. This header object should contain a sessionToken. When using this code I can see ‘Logon successfull’ at betfair.com (under Account -> Security).
Maybe you have an idea.
This code works when using in a dektop application, but not in Windows Mobile 6.

All the best, Loocie

I haven’t seen that happen before. Could you show me some sample code that exhibits the error (anonymising your login credentials, of course)?

really good blog! I read you are familiar with Betfair API. Actually I am developing a Betfair mobile client for Windows Mobile 6 (.NETCF 2.0).
When calling login method I got resp.errorCode == LoginErrorEnum.OK, but the header is null. Any solutions available?

All the best, Loocie
